So sorry to hear about Maxie. When I was a teen, it was me who found our dog had passed on, also. I know you're sad that you weren't there for her but everyone is right about animals going off by themselves when they're sick. I know that doesn't make it any easier, though. There are no words to cure your heartache. Just know we're here for you. Sweet Maxie is now playing with all the other RB dogs, fit and healthy and happy.
